    I bought this bad boy to run a 3090 FE and a 3080 FE in the same computer to mine Ethereum with. It’s working great and I expect it to continue to for the foreseeable future.

    This does what it says and is stable. I'm running a RTX 3080 ti, which this should be more than enough to handle. I don't hear any fan noise as it has never gotten hot enough for the fan to turn on. Some feedback for the Corsair. The first concern I have is the length of the cables. The motherboard cables barely fit my compact mid tower case, the Corsair 4000D, while traveling through the case's built-in wire management. They are both Corsair after all. I also wish the cables were more flexible at the ends. There are large non-flexible sections at the end where the cable transitions to the mesh sheathing. Would also be nice if they included extra, short cables for the motherboard and GPU for folks that want to use strimmers. Then again, if they just included individually sheathed cables, then I wouldn't need the strimmers in the first place. This is a problem with all PSU manufacturers, so not a problem particular to Corsair, but something they could do to differentiate themselves in the market.

    This is a pretty decent PSU, but i would have prefered the RM1000x Shift. Otherwise, this is a great PSU. Not much else to say apart from it's almost always in stock.

    This power supply is perfect for what I need. My last one died, so I had no chill in shilling out for the 1000w Gold. Hasn't failed on me since.

    Bought this to upgrade from an rm850x that was struggling to power my 3080, this immediately fixed the coil whine i was experiencing. Three dedicated PCIe cables is a win
